This report is the result of a preliminary study of the economic prospects and technical limitations of various multibarge systems potentially suitable for operation in unprotected waters. Particular emphasis has been placed on coastal, short-sea, and feeder applications of these systems, where a high degree of flexibility and intermodality is desirable. The systems considered include well-known hardware, such as the LASH concept, a LASH-compatible feeder vessel (FLASH), as well as conjectural systems of various types. These include multibarge flotillas with articulated or flexible coupling devices, modular vessels, and rigid-frame barge integrators. A qualitative discussion of generalized service patterns, terminal operations, cargoes, and cost-assignment decisions especially applicable to multibarge systems is included, together with specific technical information pertaining to each distinct type of system. An economic comparison and sensitivities to certain design parameters are presented for a sample complex route. Finally, detailed synthesis models, including performance, towboat assignment, weights, and cost estimates are provided for three promising multibarge-feeder concepts: barge-carrying (LASH) vessel, float-on LASH feeder (FLASH), and multibarge flotilla.
